        C016-blaster-stem-kids

        Blaster

        Try the Blaster Pressure Study!

        Create a ping-pong ball Blaster. Use air pressure to launch your ping-pong ball and see how far it goes!

        C016-spoolracer-stem-kids

        Spool Racer

        Try the Spool Racer Potential and Kinetic Energy Study!

        Build a spool racer. Decorate the spools with supplied racing stickers to customize your racer. Wind up the racer and watch it go! Note that too much winding will cause erratic racer behavior and will take it off course.

        C016-gumdrop-stem-kids

        Gumdrop Bridge

        Try the Gumdrop Bridge Structural Integrity Study!

        Challenge yourself by building a bridge capable of holding a textbook using only candy gumdrops and toothpicks. This activity will require you to think through the engineering aspect of load distribution while also touching on the mathematics of how different shapes affect the strength of a structure.

        c016-catapult-stem-kids

        Catapult

        Try the Catapult Structural, Potential and Kinetic Energy Study!

        Build a catapult with popsicle sticks, a spoon and rubber bands to launch a ping-pong ball. Try different catapult designs and see how it affects the distance your ping-pong ball will go!
